Abstract (en)
[origin: US2022268649A1] A torque measuring device includes: a magnetostrictive sensor having a ring-shaped holder arranged around a magnetostrictively affected section of a rotating shaft, a detecting section embedded in the holder and that changing a voltage according to a change in magnetic permeability of the magnetostrictively affected section; and a sensor-side engaging section; and a fixed member having a fixed-side engaging section, the fixed member not rotating even during operation. One of the sensor-side engaging portion and the fixed-side engaging section is a convex section and the other is a concave section. With the sensor-side engaging section and the fixed-side engaging section engaged with a concave-convex engagement, shifting of the position of the magnetostrictive sensor in the direction of rotation and the radial direction with respect to the substrate is prevented.
